UNTAN - Dean of the Faculty of Mathematics and Natural Sciences Pengatahuan Tanjungpura University (Natural Sciences-Untan) Pontianak, Dr. Thamrin Usman, who is also the Chairman of the Committee for preparation of draft regulation Classification
Water Quality of Rivers in West Kalimantan said based on the findings while there are several points along the Kapuas River is so polluted by harmful chemicals.
To menindaklajuti findings, he was with the team preparing the draft regulations will do in the Kapuas river water classification into four classes namely class I, II, III and IV. The focus of the research team for the first step will be done along the Kapuas River.
"We will carefully whether the Kapuas River water are classified Class I, II, III or IV class," he said.
If the Kapuas River is still classified as grade I entered the Kapuas River water is still feasible to be used as raw material for water taps. But if water has entered the Kapuas River classification class II to class IV then, Kapuas water is not fit for use as raw material for the taps. "Water has entered the Kapuas classification class II to class IV, let alone to PDAM raw materials, used for the pool or fishing and agriculture alone is not permitted," he said.
To classify water Kapuas, the team will use several parameters such as substance mercury, volutan level, turbidity and the level of biological contamination. If water has entered the Kapuas II-class classification, the taps must be prepared to change their raw materials. Because if still using the Kapuas water will be very dangerous for health.
During this time, water utilities that use raw materials Kapuas water with very low operational cost of Rp 10 per cubic meter. These costs could have increased operating costs by five times, if the taps changing their raw materials by buying water or take water mountains.
According to Thamrin, the operational costs to increase when water is not too Kapuas is not fit for use as raw materials. PDAM to improve water filtration technology Kapuas before sale to consumers.
"For that, we ask taps immediately prepared a new technology such as digital protection or prophylactic filter harmful chemicals that are soluble in water Kapuas," he begged.
Determination of the Kapuas river water class classification, according to Thamrin no
can be done by examining some point. For no one can say that one point of the Kapuas river water contaminated by the overall water will be polluted Kapuas. "Therefore, we will carefully as a whole along the Kapuas river," he said.
Thamrin disclosed, the initial step that will be the team that inventoried the interim analysis data that already exist in several districts. The data will be studied, corrected, is it true some point mentioned the Kapuas river had actually been contaminated. The team will check into the field and will be concluded into the class how many of each point. When you enter the class II, the team will coordinate with nearby users, especially PDAM and local communities to discuss solutions that must be done together in anticipation of river water pollution.
"We will ask the local district taps where water had entered the class II, if the taps are ready to replace the raw material water. If not ready, the taps must promptly update the appropriate technology to intercept or filter out harmful substances, "he said. In addition, the discovery team will be a recommendation to the government in making policies to reduce water pollution Kapuas River.
